TUBE-VULCANIZER.

Specification of Letters Patent. Patented Sept. 12, 1916,

Application led October 22, 1915. Serial N0. 57,351.

To all u'zomt ymay concern:

Be it known that I, CAssELL D. Hines, a citizen ot' the United States,residing at Fort lYorth.. in the county of rl`arrant and State of Texas,have invented certain new and useful Improvements in Tube- Yuleanizers,ot' which the following is a specilication.

My invention relates to vulcanizers, and more particularly tovulcanizers for repairing inflatable tires; and the object is to providea device which is simple in construction and convenient for operating ontubes of rubber for tires and other articles and which is strong anddurable and simple in operation.

Another object is to provide a plurality of pressure plates all adaptedto rest against a tube plate and to provide means for keeping the tubeplate constantly7 hot.

Another object is to provide ready meansfor dryinlT the Other articlesprior to vulcanizing. objects and advantages w1ll be fully 'explained inthe following description and the invention will ,be more particularlypointed out in the claims.v

Reference is had to the accompanying drawings which form a part ot thisapplication.

Figure l is a front elevation of the machine. F ig. 2 is a brokensectional view, taken substantially on the line of Fig. 1. Fig. 3 is adetail view of the adjustable weight. Fig. i is a perspective view ofone of the pressure pads. Fig. 5 is a vertical cross-section of thesame, taken on the line y-y of Fig. 1. Fig. 6 is a broken view,Aillustrating the use 'of a spring instead of a weight for controllingthe pressure pads.

Similar characters of reference are used to indicate the same partsthroughout the several views.

The machinel is provided with and 2 which can be sufficiently braced bythe rod or shaft 3 and the tube plate 4 and the rest bar 5. The rods 3and 5 may be uprights 1 provided with lock nuts' 'for holding the framerigid.' The tube plate 4 is mounted rigidly Ain the frame pieces 1 and 2and is set on one corner to make the condensation of steam collect at apoint below the appli cation of the pressure pads so that thecondensation will not interfere with the propercuring of the rubber.Provision may be made for draining the condensation, as by a drain cock7. The tube plate may be supplied with steam through a pipe 8. The

upper side of the tube plate 1 is made concave to receive 4thecompressed air pipe'9 which receives compressed air from some supplysource through a pipe 1o which is provided with a cock. T he air in thetube 9 will be heated by the hot steam in the tube plate 1 and is usedfor drying cement. as will be further detailed later. The bottom of theJtube plate forms the pressure and heating surface against which therubber tubes are pressed for curing.

A plurality of pressure pads are provided and these pads may be ot'different sizes, as the pads 12 and 13. Fach pad is made of a metalframe 1.1L and asbestos plates 15 and 16. The plate 15 is bolted to themetal plate 14 and the plate 16 is attached to the plate 15 by cement orother plastic attaching ma-4 terial. rThe plates 15 and 1G may beasbestos, cloth, rubber, or any suitable material that will not mar theinner tube. The plate 14 has depending ears 17 for attachment to a lever1S, a lever being provided for each pad. The levers 1S are fulcrumed onthe shaft or rod 3 and the'lower arm ot' each lever is provided with apedal 19 in convenient reach of the foot ot' the operator. There is auadvantage in having the axis or fulcrum of the levers between theoperating weight or spring and pressure pad. An adjustable weight 2O ismounted on an arm Q1 which is integral with the lever 1S, a weight beingprovided for each lever. IThe weights press the pads 12 or 13 againstthe. rubber to be `vulcanized. A substitute for each weight mayfbe aspring Q2 which is connected to the arm r21 and to a bar 23 extendingacross the machine. when the operator puts his foot on a pedal 19 andpresses down. the level-'1S will stop against the rest bar 5 and remainthere while the operator adjusts `the. rubber tube on the pad. Inoperation, the operator can attend to a number of pads and have a numberof rubber tubes curing at the same time.

Another advantage of the machine is the provision for drying the cementwhich is used in closin the cavities. The rubber cementv is dried y hotair. A hose 21 is connected with the compressed air pipe 9, whichcontains heated compressed air, receiving its heat from the tube platei. The ho'se 24 is provided with an air cock or other device 25 forconvenience in turningA which can be cured on a, tial; plate, such tethe article and the cocks opened. The compressed air is readjvv te dri7whateve article is necessari Y.

The triple armed lever 1S provides for quick action in locating the padand for' placing the article to be treated on the tube plate to bepreseefl. by the pad. The lever is operated bv the foot 'and the rest ilprovided so that the foot can hold the lever stationarv vv'hile thearticle to be treated is located. when the article iS located, the footis removed and preseure isv applied automatically. The spring vvill.operate in the salue manner. The tube plate l is kept hot b v eteaniand is alvvaye` really ler action at any 'point thereon.

Various changes may be made in the constructionl of the several parte`without departing' troni my invention. The niunber oi pads mayY beincreased or decreased. The pads may be manipulated by hand as wellv asby the lfoot b v ueing the handle Q6.

The machine herein described is capable of general application forvulcaniffingr rulber tubes and various other rubber articles rubber bagsand rubber boots.
